Connect to the Data Network

The 10BASE-T MDI-X port connects the Megabit Modem CRA-C to the data
network. If the data network has an MDI-X port, use the yellow cross-over
Category 3 or better cable. If the data network has an MDI port, use the black
straight-through Category 3 or better cable.

Table 5 and Figure 5 show the 10BASE-T Ethernet interface data signals for
both MDI and MDI-X configurations.
